  • the purpose of the present invention is to design an aircraft tire which is lightly worn during landing, can prolong the use time, and can reduce the risk of accidents.
  • at least two protruding wind ears are respectively designed on two sides of an existing aircraft tire body, and the wind One side of the ear is provided with a concave structure, and the direction of the concave structure on the wind ears on both sides of the carcass is the same.
  • the wheels can be rotated before the aircraft lands, so that the rotation speed of the wheels is equal to or greater than the speed of the relative movement of the aircraft and the runway, that is, the wheel speed is consistent with the ground speed, eliminating the 3 ⁇ 4 degree difference between the wheels and the runway , From sliding friction to rolling friction, thereby greatly reducing the wear on the tire and extending the life of the tire.
  • Each wind ear can be designed with a pyramid or other shape. When it is a pyramid, the outer surface of each wind ear is a pyramid.
  • the angle of the point of force on the surface connected to the carcass is located at the most axial position of the carcass. Wide place.
  • the outer angle of the present invention may be located at the edge when the amount of compression of the carcass is maximum; the inner angle thereof faces the central axis of the carcass.
  • the distance from the inner angle to the outer angle and the angle of the impact point is preferably greater than the distance between the outer angle and the angle of the impact point.

Abstract

L'invention se rapporte à un type de pneu pour aéronef qui se compose d'au moins deux pales de part et d'autre d'un pneu conventionnel, chaque pale présentant un évidement sur son côté et chaque évidement étant orienté dans la même direction. Ce type de pneu doté de pales fait en sorte que les roues de l'aéronef tournent avant d'entrer en contact avec la piste de décollage. La vitesse de rotation des roues est égale ou supérieure à la vitesse relative entre l'aéronef et la piste de décollage. Plus précisément, la vitesse des roues est identique à la vitesse d'atterrissage. La vitesse relative entre les roues et la piste de décollage peut être supprimée. Grâce à la transformation de la résistance au glissement en résistance au roulement, il est possible de réduire considérablement les dommages causés au pneu et de prolonger la vie utile des pneus.
